<p class="bodytext">If you host a web site on this server and have a standalone DNS server acting as a primary (master) name server for your site, you may want to set up your control panel's DNS server to function as a secondary (slave) name server:</p>
<ol class="procedurelistnumber"><li class="procedurelistnumber">Go to <strong class="specialbold">DNS Settings</strong>.</li><li class="procedurelistnumber">Click <strong class="specialbold">Switch DNS Service Mode</strong> in the <strong class="specialbold">Tools</strong> group.</li><li class="procedurelistnumber">Click <strong class="specialbold">Add Record</strong>, specify the IP address of the primary (master) DNS server, and click <strong class="specialbold">OK</strong>.</li></ol><p class="bodytext"></p>
<p class="procedureheading">To make the control panel's DNS server act as a primary for a zone:</p>
<ol class="procedurelistnumber"><li class="procedurelistnumber">Click <strong class="specialbold">DNS Settings</strong>.</li><li class="procedurelistnumber">Click <strong class="specialbold">Switch DNS Service Mode</strong> in the <strong class="specialbold">Tools</strong> group. The original resource records for the zone will be restored.</li></ol><p class="bodytext"></p>
<p class="bodytext">If you host a web site on this server and rely entirely on other machines to perform the Domain Name Service for your site (there are two external name servers - a primary and a secondary), switch off the control panel's DNS service for each site served by external name servers:</p>
<ol class="procedurelistnumber"><li class="procedurelistnumber">Click <strong class="specialbold">DNS Settings</strong>.</li><li class="procedurelistnumber">Click <strong class="specialbold">Switch Off the DNS Service</strong> in the <strong class="specialbold">Tools</strong> group. Turning the DNS service off for the zone will refresh the screen, so that only a list of name servers remains.<p class="listnote"><strong class="buttons">Note:</strong> The listed name server records have no effect on the system. They are only presented on the screen as clickable links to give you a chance to validate the configuration of the zone maintained on the external authoritative name servers.</p>
</li></ol><p class="procedureheading">To validate the configuration of a zone maintained on authoritative name servers:</p>
<ol class="procedurelistnumber"><li class="procedurelistnumber">Click <strong class="specialbold">DNS Settings</strong>.</li><li class="procedurelistnumber">Add the entries pointing to the appropriate name servers that are authoritative for the zone to the list of DNS records: click <strong class="specialbold">Add Record</strong>, specify a name server, and click <strong class="specialbold">OK</strong>. Repeat this for each name server you would like to test. </li><li class="procedurelistnumber">The records will appear in the list.</li><li class="procedurelistnumber">Click on the records that you have just created. Plesk will retrieve the zone file from a remote name server and check the resource records to make sure that domain's resources are properly resolved. </li><li class="procedurelistnumber">The results will be interpreted and displayed on the screen.</li></ol><p class="bodytext"></p>
